At present, hazardous waste recycling industry is still in the initial stage in our country , reverse logistics rarely involve the hazardous waste, whether in law, or from the size of the enterprise and the recovery in the recovery process, pared with the developed countries still has very big disparity. So if we want to make some achievements in the hazardous waste recycling and reuse, our country must pay attention to various laws and regulations of the hazardous waste and the unique of hazardous waste. The definition and type of hazardous waste, the existing problems and recycling and reuse system and reverse logistics work system are analyzed in this paper, and analyzed the current hazardous waste reverse logistics and the disadvantages of the corresponding three models in detail, namely enterprise joint recovery mode, enterprise independent recovery mode. Owing to the unique of third party reverse logistics system analysis, this paper analyzed this mode in detail, and constructed the model concerning how to plan the work according to the characteristics of this pattern, and the feasibility of the model and the accuracy of the models was analyzed and verify bined with 31 main cities, and carried out the simulation of Witness bined with the process of the international unobstructed type of drinks beer packing material recovery and reuse. Key words: hazardous waste, reverse logistics, the work planning, artificial immune geic algorithm, the simulation of the Witness i 目 錄 前 言 .......................................................................................................................................... 1 1 緒論 ........................................................................................................................................ 3 研究的背景 ................................................................................................................. 3 研究的目的 ................................................................................................................. 3 2 有害廢棄物及逆向物流 ........................................................................................................ 5 國內(nèi)外有害廢棄物存在的問題分析 ......................................................................... 5 有害廢棄物定義 .............................................................................................. 5 有害廢棄物分類 .............................................................................................. 5 有害廢棄物存在的問題 .................................................................................. 7 目前我國廢棄物運(yùn)作施行情況 ...................................................................... 8 國內(nèi)外有害廢棄物運(yùn)作法規(guī) .......................................................................... 8 逆向物流 ..................................................................................................................... 9 逆向物流定義 ................................................................................................ 10 逆向物流成因 ................................................................................................ 10 逆向物流的分類 ............................................................................................ 11 逆向物流的特點(diǎn) ............................................................................................ 11 逆向物流的原則 ............................................................................................ 12 逆向物流的重要性 ........................................................................................ 13 企業(yè)逆向物流系統(tǒng)框架 ................................................................................. 14 3 逆向物流模型的建立 .......................................................................................................... 15 回收物流中心選址模型 ........................................................................................... 15 免疫算法( Immune Algorithm, IA)的基本思想 ..................................... 15 問題描述 ........................................................................................................ 17 解決基本思路和求解步驟 ............................................................................ 18 仿真實(shí)驗(yàn)及結(jié)果分析 .................................................................................... 20 基于 Witness 的有害廢棄物回收物流仿真系統(tǒng)設(shè)計(jì) ............................................ 22 數(shù)字仿真軟件 Witness 簡介 ....................................................................... 23 Witness 用戶界面 ........................................................................................... 23 Witness 建模與仿真過程 .............................................................................. 24 仿真模型的設(shè)計(jì) .......................................................................
